18QHTF21-48.0048-PD

Oscillators Overview

The 18QHTF21-48.0048-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd, operating at a nominal frequency of 48.0048 MHz. It utilizes LVCMOS output logic and functions with a 1.8V supply voltage. The device features a Standby (Power Down) control mode for power management. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• LVCMOS output interface
• Standby (Power Down) control capability
• Compact 4-SMD No Lead package

Oscillators Applications

• Precision timing circuits
• Digital signal processing systems
• Communication equipment

Oscillators Procurement Notes

Verify the specific suffix 'PD' indicates the Standby function as documented. Confirm the 1.8V supply requirement matches system design. Ensure the 4-SMD footprint aligns with PCB layout constraints. Check datasheet for tolerance specifications before integration.

Oscillators Selection Notes

Select this component when a 48.0048 MHz clock source with low voltage operation is required. The Standby feature supports power-sensitive designs. Compare against OE variants if Enable/Disable functionality is preferred over Power Down. Verify package dimensions for mechanical fit.

Oscillators Part Context

This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics. The series offers various frequencies and control options. The PD suffix specifically denotes the Standby mode, distinguishing it from OE (Enable/Disable) or uncontrolled variants within the same family.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 models with identical frequency and package but different control modes, such as 18QHTF21-48.0048-OE, if functional differences are acceptable. Cross-manufacturer replacements require matching electrical parameters and pinout compatibility.
